Amazon S3 Reviews Summary
Author infoRatingReview Summary
Data Engineer at a tech vendor with 10,001+ employees4.5I've used Amazon S3 for over three years to manage company data migrations; it offers excellent scalability, reliability, and integration with AWS tools, though restore speeds from Glacier and cost visualization could be improved.
Senior Data & AI Engineer at Imprint5.0I've used Amazon S3 for data lakes and file storage, appreciating its tiering, stability, and features like S3 Inventory. Setup is easy, support is excellent, though I find the global bucket naming restriction somewhat limiting.
Cloud engineer at a tech services company with 11-50 employees4.5I primarily use Amazon S3 for storage, valuing its cost optimization and lifecycle management that transitions objects between storage classes. However, integrating with services like Elemental MediaConvert requires better documentation, as current resources are difficult to comprehend.
DevOps Engineer at Stellar Tech4.0I use Amazon S3 for storing files and appreciate its global accessibility, data cataloging capabilities, and scalable storage. However, setting it up can be difficult due to unique global naming conventions, which could be improved by allowing names linked to personal accounts.
Solution architect at SM Supermalls4.5I’ve used Amazon S3 for about 10 years, appreciating its flexible setup, scalability, and integration with AWS tools, though I believe AWS should establish a Philippine region to resolve data locality issues and improve service efficiency.
AWS Consultant at Virtual University5.0I use Amazon S3 for storing structured and unstructured data, finding its scalability, reliability, and security features crucial. Its cost-effectiveness and high-speed performance suit my needs, though I wish it supported larger data uploads beyond five terabytes.
CTO at Atulya Abhinav Tech Private Limited5.0I primarily use Amazon S3 for file storage, referencing them in my database for processing. Its scalability and archiving capabilities are valuable, though data retrieval can suffer latency with large files.
Information Security Analyst at a financial services firm with 201-500 employees4.5I have been using AWS Cloud since 2021, focusing on S3 for its storage and integration features. While its security could be improved, understanding storage classes enhances ROI. Although I have Azure certifications, I currently prefer AWS.
